there are trainers then there are trainers that can do more after you learn.may take you a little longer to master but you will be way ahead of others afterwards.a basic trainer use a flat bottom wing is a high wing configuration and is either 3 channel [rare these days] or 4 channel.the nest step up is a trainer with a high wing or shoulder wing that uses either a symetrical or semi symetrical airfoil,these will let you do aerobatics,not precise like a pattern plane but respectable.35 years ago when i started every one was fling h-rays or kadets as 3 channel.andrews had the a ray which was a 4 channel trainer but it was out of production when i wanted to start building.arf did not exist.back then manufactures ran production runs of kits that were supposed to last six months.i did not want to wait for the next run and bought a falcon 56 and an os 35 r/c for power.radio was a 4 channel series 70 .my dad at the time thought i may have made a mistake because no one at the field was flying a falcon 56..the only mistake i mae was building it per plans,it did not have a steerable nose wheel and it took a while to install a modification.bought the kit in october.had it finished in december,added the sterable nose gear and was ready for test flight and first lesson the 2nd sat in jan 1971,field was 30 miles from home one way.did not have licencse so dad had to drive me every sat and sunday for 4 flights each day if i was lucky as back then there was a shortage of instructers and only 3 planes wre allowed in the are at the same time and only 5 frequencies avaiable on the 72 band.soloed easter sunday of that year but i was able to do inverted flight,cuban eights,spins,hammerhead stars,top hat almost the full pattern.that plane weighed 5 1/4 pounds covered in silk and dope.could fly in strong winds when others would not even attempt to fly.,still flys today after recovering with monokote and now weighs 3 3/4 pounds.2nd plane was a vk cherokee with retracts and 3rd plane was a p-51.learn the basics first and you will have you plane a long time.
